How to take good photos and how to use the aperture?

The so-called good photos have two basic elements:

First, the density should be moderate, that is, the scenery is neither too dark nor too bright;

Second, the composition should be reasonable, that is, the picture should be stable and beautiful.

About aperture:

Its basic function is to control the amount of light entering with the shutter.

So as to obtain photos with the required density.

Aperture is usually expressed by the coefficient of the ratio of lens focal length to aperture:

……4.5、5.6、8、 1 1、 16……。

For example: 8, that is, the focal length of the lens is 8 times the aperture of the aperture.

The focal length of an ordinary lens is fixed,

That is, the larger the aperture coefficient, the smaller the aperture of the aperture.

The less light enters, in order to achieve the same exposure,

The shutter speed will slow down.

When choosing a specific aperture, we should consider the specific situation.

Cooperate with the shutter to achieve correct exposure.

For example, when shooting a moving object, we must first determine the shutter speed.

Use the aperture to adapt to the shutter to get the correct exposure!

Of course, the aperture has other functions,

For example, adjusting the aperture size can control the depth of field and so on.

When I was studying photography, I used the benzene method:

Record the time, weather, aperture, shutter and the scene at that time.

Summarize the experience by comparing the results of printing photos.

Practice proves that this method is very useful.

You can make the exposure basically correct in a relatively short time! ! !

Of course, the above is a narrow understanding of correct exposure.

If we further understand the correct exposure in a broad sense,

It should be said that only those that meet your creative intention can be correctly exposed!

High-profile and low-key photos are common.

The so-called high profile means that the subject and background are very bright.

This is often the result of overexposure;

The so-called low profile means that the subject and background are very dark.

This is usually the result of underexposure.

They are often used in process photography,

You can get an unexpected atmosphere rendering effect,

Become a work of art!

I believe that after a period of practice,

You can also make practice perfect,

From the kingdom of necessity to the kingdom of freedom! ! !
